Early April Fool's joke?

The intention, I believe, is to reduce or eliminate unwanted frequencies beyond our hearing range, because with digital replay these can intermodulate with the wanted frequencies that we do hear. That manifests as noise or ‘hash’, which these filters are designed to eliminate. Hence you enjoy better replay of the range you can hear.

It’s the RA Mini Zap that deals with the RF noise that can modulate a digital signal, and that’s what I wrote about.

Hi,
Any alleged digital modulation is removed by the receiver. If the RF is supposedly modulating the digital signal, then you will get bit errors and hear those. There is no intermodulation occurring appearing in the audio band.

The RF mini zap specification is not given on the RA website. Without that, i would NEVER use them for blanking any output.

I am not sure how they could be used to stop any alleged digital modulation by RF noise if they blank an output. Blanking an output implies the output is not used.

Shadders.

I know many of these type of device aren’t ‘supposed’ to do anything according to the technical design of the relevant product or system, but there are enough reports - and claims by their makers - to suggest they might do something.

As you note, they seem to be recommending them for use in a spare input. A bit like some mains devices that sit in a spare socket. But I don’t claim to understand how they work, or whether they do, but I’d be willing to try them. Where self-delusion starts to have an effect I’m not sure!

Hi,
If this is subjective responses, then that is not a good indicator that they do something.
From the RA website :
"fitted to ‘blanking’ plugs specifically for connecting to the outputs of any piece of equipment. They are perfect for unused tape outputs and pre-outs on an amplifier, or unused coaxial digital outputs on CD, DVD or Blu-ray players, and the outputs on the back of your TV."

As you note, they seem to be recommending them for use in a spare input. A bit like some mains devices that sit in a spare socket. But I don’t claim to understand how they work, or whether they do, but I’d be willing to try them.

RA states using them for outputs. I would not use them for any output unless you know the impedance used in the RA product.

For spare inputs, then yes, all you need is the cheap grounding RCA plugs.

Where self-delusion starts to have an effect I’m not sure!

If they are used on outputs, then that self delusion is immediate....

Shadders.

There will always be rich clueless people..... Unfortunately.
